中文摘要：

通过试验，探讨了生物过滤对饮用水源中微量有机物的去除效果与特性．结果表明，生物过滤可有效去除饮用水源中的微量有机污染物；滤料介质对生物过滤效果具有一定的影响，加氯水反冲洗对生物过滤具有明显的负面影响；活性炭、石英砂双层滤料生物滤柱可较大幅度地去除苯酸酯类、脂肪酸酯类和酚类等有机物．

英文摘要：

This paper presents the research examined removal effects and characteristic of trace organic matter in drinking water with by means of experiment. The result indicated the biofiltration could remove trace organic pollutants effectively. The filter media had obvious influences on biological filter. Backwashing with chlorinated water had negative effect on the biofilm obviously. The GAC-sand biofilter could remove benzoic acid esters, aliphatic acid esters and phenols in the influent of the biofilter effectively.
